PYREX 500 ml Heavy Wall Filtering Flask with Sidearm Tubulation - Lot of 3 Flasks

Heavy-Duty Vacuum Filtration for Safe and Efficient Separations

Upgrade your laboratory's filtration capabilities with this reliable set of three (3) Pyrex 5340-500 Heavy Wall Filtering Flasks. Specifically engineered for vacuum filtration, these 500 mL Erlenmeyer-style flasks feature heavy-wall borosilicate construction, designed to safely withstand the rigorous pressure differentials required for liquid-solid separations without the risk of implosion.

Each flask is equipped with a robust glass sidearm tubulation, allowing for the quick and secure attachment of standard vacuum hosing. Manufactured from Corning’s legendary Code 7740 borosilicate glass, these filtering flasks offer exceptional resistance to chemical corrosion and thermal shock, making them an indispensable tool for everything from routine media filtration to complex analytical extractions.

Key Features & Benefits

• Heavy-Wall Construction: Specially blown with significantly thicker glass walls to safely handle standard vacuum pressures, minimizing the risk of implosion during active filtration.
• Integrated Sidearm Tubulation: The sturdy glass sidearm provides a secure connection point for vacuum tubing, ensuring a tight seal for efficient suction.
• Legendary Pyrex Durability: Crafted from low-expansion Code 7740 borosilicate glass, offering maximum protection against harsh chemical reagents and sudden thermal changes.
• Erlenmeyer Geometry: The wide, flat base provides excellent stability on the benchtop, preventing accidental tipping while supporting heavy Büchner funnels.
